Never seen one of these...

I am hoping somebody can tell me what in the world this thing is? It is to the right of the bigger and smaller mushrooms...it looks to be some sort of pest anemone, though it does not match any of the pictures I have seen. It's tentacles have a barbed appearance and they curl inward to the mouth randomly. Its mouth is red and white. Has anyone seen one of these or know what it is? The pictures do not show as well as they do on my phone

Maybe a brittle star?  I use the following site to identify strangers that show up in my husbands saltwater tank...maybe you already have it but if not...

I think that's what it is! I didn't even consider anything else other than some type of anemone. It has moved and I don't know where it is now. Than you very much
